As part of the pond remodel I have plans on adding extra air to the bio chambers. Whilst running the plumbing I wondered about actual air flow due to friction loss in the piping as well as that due depth of water. Has anyone ever used an air flow guage to meter the amount of air flowing or to check how much air is actually flowing? AES sells a pitot tube type water flow meter and the company that makes that particular one has others that can meter air flows in the ranges that we like to use. Can not remember the name of the company right now and can not find where I filed the product information I downloaded. The ones I am talking about are the clear acrylic ones with flow measured from a pitot tube placed into the water line.
